A rare ruby is expected to attract attention at London Aim-listed Gemfields’ upcoming ruby auction.
The 40.23-carat rough ruby, unearthed at the company’s Montepuez deposit, in Mozambique’s north-east Cabo Delgado province, is expected to set a new bench- mark for the quality of African rubies.
Gemfields, headed by Ian Harebottle, has had the ruby appraised by Gübelin Gem Laboratory of Switzerland, which has remarked on the gem’s transparency and colour, and jewellery historian Joanna Hardy on its impressive size and quality.
The rough ruby will be sold to the highest bidder at next month’s auction in Singapore.
